I use film because it's where I began my photography. I still like using film and I develop film and print in a darkroom I have set up. I only do this for fun. There are some really nice people here on APUG and I enjoy reading and participating here.
Sorry to report to you, for my business I'm 100% digital. That's the way it is now. After working in another field for about 30 years, I started a photography business back in 2002 and it's been my full time business since then. I started with film and I thought it would work for my business until I no longer could breathe! Gosh, I was wrong!
I joined our local Professional Photographers Association in 2002 and 95 to 98% of the pros back then were making pictures with film. As time went on digital crept in and now 99.9% of pros are now using digital capture. In 2003-04-05 we would get a person putting on a seminar asking, "how many are film? how many are digital?" And back then clients would ask me which I used.
Today nobody asks. Matter of fact for the type of photography I do, which is people photography, they want digital as they can see some samples immediately and they know now all the things that can be done with programs like Photoshop. Of course these things can be done with film if you scan the negatives and/or transparencies. One of the options I offer to wedding clients is the ability to take photos from the time people are getting ready through the ceremony and into the receiving line and show a select group of photographs as a slide show at their reception.
At any rate, film is nice and this is a good place to learn about using film for your photography.
My suggestion, as far as a career is concerned, is have a day job and try getting your photography going and see if it's what you want to do as a career. See if you can earn any money with it. It is a very competitive business now, no matter what piece or pieces of photography you want to strike out on and possibly make a living.
If you decide to go the photography career path, please take classes on how to operate a small business, how to sell, how to market your business and how to live on a low income until you get your business up and running. The PPA (ppa.com) offers classes on this as well as classes on the various aspects of photography you will need for your business.
Good luck & welcome to APUG.
